I have a 6809 card called 'The Mill' in one of
my Apple ][s. It seems to
have come in 2 versions -- the cheaper one, which I have, doesn't have a
ROM on it, and is used with a modified UCSD p-system. It thus speeds up
Pascal and Fortran programs, but it otherwise not that interesting. The
more expensive version of the card had a boot ROM on it, and would boot
OS-9 (obviously configured for the Apple, and put on GCR disks). I now
wish I'd got the latter version...
It seams like there are several different ROMs
available - or schould we call it different cards ?
I have at least one version with a ROM to suppurt
the Mumps system.
It's a pretty simple card. The 6809 CPU, a few bus
buffers, and a bit of
TTL glue.
Like the original Softcard - a bit glue logic to
adapt the signaly and take over the whole system
(inhibit the 6502). There was also a 6809 Card
with seperate Memory, I just don't remember the
name.
